Breaking News: A federal appeals court declined a Trump administration request to order California to set aside about 20,000 ballots.

This report is genuinely overwhelming, in terms of the evidence both against Trump and of a ham-fisted cover-up. Including one instance in which Ghislaine Maxwell was actually about to mention one of Trump's young accusers and Todd Blanche told her to stop talking.

Sorry, correction: Not sure why this isn't a bigger story, but I read this entire report today. It's absolutely gutting. Multiple accusations that Trump and Epstein worked together to rape and assault young women, most of them very, very credible. democrats-judiciary.house.gov/media-center...

“If AI continues to improve at present rate, then in a few years, there’ll be nothing human mathematicians can do that AI can’t do better” can professors please stop spreading doom. It affects undergrads & isn’t the whole point to keep future generations inspired & enthusiastic so fields dont die??
This guy is a terrible teacher, even if AI can solve problems, people still have to learn and strive for a better world, not just leave it up to the paperclip optimizers.

JFC--they are telling us to turn over one of our most important tasks as researchers to AI. This is appalling. I also imagine someone is making money here......
How can AI support researchers in peer review? Springer Nature and Google DeepMind are partnering to co-design an AI peer review assistant that helps reviewers navigate manuscripts and focus on where their scientific judgement matters most. Learn more: spklr.io/63320EVgT8

To build complex tissues, cells need to produce energy to grow, generate forces and modulate mechanical properties. The role of metabolism and tissue mechanics in development is experiencing a renewed interest. Yet, we know very little about how these systems interact to drive morphogenesis...

If Brazil can do it so can we. Democracy is not inevitable, we have to put in the work to make it happen.
The mobilization itself was already not something I ever expected to see, but to actually win? Hell, to double the winning margin from the 2022 runoff? Genuinely surreal. Maybe child raping billionaires *don't* have to run the world with a shit-eating grin. Maybe that can stop.
